I nearly made my third mistake on my first embark in this dungeon - first was not embarking on evil biome, second was embarking in non-goblins area and I was very close to choosing embark without human/elves. Well anyways that fort prospered and despite 4 vamps I managed to caught and occasional were-beast raid I reached the population of 200. I even managed to survive dreadful Giant Mosquito Hordes (eventually they dropped from 170+ to 0). I was just about to start punching through the aquifer on the other side of the map in order to make a massive, glass roof statue garden few dozen z-layers bellow, when I decided to try a new embark.
Fearlessly, I embarked on 2x2 site with 1 square in terrifying biome.
And got promptly raped by Undead Giant Mosquito Hordes in my first few minutes.
In next fort a Forgotten Beast made out of SNOW managed to enter my irrigation tunnels and reach through the well one layer above and grab my only strand extractor.
Who then politely bashed it's head in, needing only three strikes. Probably a vampire, yes.
I also learned that mountains without ANY kind of metal/flux stone listed on embark site are, indeed, more devoid of metal than country music.
While I could, surprisingly, live with that as it meant more challenge, massive migrant waves (despite making exactly zero crafts/smoothing (ofcourse, then I remembered I already reached twinkly blue metal)), a lone berserk fish dissector and a fort full o elk birds on the loose due to unsealed cavern entrance just made me think of a new way to try and play DF.
I never before relied heavily on burrows, time to try some caste-oriented fort building!
